The Conversation

I always love a story where new technology sheds light on a historical mystery.

UCLA archaeologist Justin Dunnavant and his colleagues are using mapping technology that has become available only in the past few years to find a 300-year-old settlement of escaped slaves, known as Maroons, on the island of St. Croix.

Until now, the only accounts of these Maroons are from the perspective of Danish settlers and missionaries. The evidence of the Maroon settlement Dunnavant is searching for will help fill in the story from the perspective of the escapees themselves. It could also shed light on how they managed to make a life for themselves while hiding from the Danish settlers in the most difficult terrain on the island.

The timing of this search is important: Just this month, the local government purchased the acreage where the settlement is believed to be located and designated it a U.S. Virgin Islands Territorial Park. Archaeologists hope to use any artifacts they find to create an exhibit that will honor the legacy of the Maroons.

As many as 10% of enslaved people on St. Croix escaped. Where they went has remained a mystery, but scientists are using new mapping technology to find answers.

Manufacturers often make bold claims about how well these technologies work. Better testing would allow consumers and institutions to pick the most effective ones.

Even though you may mostly hear about fires in the US, Canada, Europe and Australia, it’s Africa that has far and away the most acreage burned and people exposed to fire.

How federal officials talk about health is shifting in troubling ways – and that change makes me worried for my autistic child
